The problem of determining a sparsest cut in a graph is characterized and its computation shown to be NP-hard. ...
A class of sparsest cuts, termed bottlenecks, is characterized by a dual relation to a particular polynomial time computable multicommodity flow problem. ...
For the partition A, A of V, the cut (A, A) denotes all edges with one end vertex in A and the other in A. ...

This problem is formulated as a Multi-level Bottleneck Assignment Problem (MBA). The MBA problem is studied: it is shown that it is NP-complete and an asymptotically optimal algorithm is presented. ...

We propose a new approach based on a novel speed-up of the isoperimetric algorithm [1] that can solve the problem of leaks through a bottleneck. ...
The speed enhancement converts the isoperimetric segmentation algorithm to a fast, linear-time computation by using a tree representation as the underlying graph instead of a standard lattice structure ...
In particular, it is known that the solution to the isoperimetric problem often partitions the manifold at bottleneck points, as exhibited in Cheeger's classic paper on the subject [21] . ...

Our evaluation illustrates that processing a 4-billion edges graph on a system with one CPU socket and one GPU, while offloading as little as 25% of the edges to the GPU, achieves 2x performance improvement ...
In particular, the workload generated by a partitioning scheme should match the strength of the processing element the partition is allocated to. ...

This paper examines a generalization of the problem, the Bottleneck Convex Subsets problem: given a set P of n points in the plane and a positive integer k, select k pairwise disjoint convex subsets of ...
We show the problem is NP-hard when k is an arbitrary input parameter, we give an algorithm that solves the problem exactly, with running time polynomial in n when k is fixed, and we give a fixed-parameter ...
Note that the Bottleneck Convex Subsets problem is straightforward to solve for the case when k ≥ n/3, i.e., one needs to compute a balanced partition without worrying about the convexity of the sets. ...
